Summary: ip6addr_aton() fails on IPv4 mapped addresses

_______________________________________________________
Details:
I was testing out some of the socket examples with an IPv4 mapped IPv6 address
and found that ip6addr_aton() fails when encountering the dotted quads section
of the IPv4 mapped address
#define SOCK_TARGET_HOST6 "::FFFF:192.168.1.16"
socket_examples_init() calls ip6addr_aton() which hits the "unexpected digit"
case when the first dot is encountered:
if (s[1] == ':') {
...
} else if (isxdigit(*s)) {
/* add current digit */
current_block_value = (current_block_value << 4) +
(isdigit(*s) ? (u32_t)(*s - '0') :
(u32_t)(10 + (islower(*s) ? *s - 'a' : *s - 'A')));
} else {
/* unexpected digit, space? CRLF? */
break;
}
